Therefore, the event-dispatching thread executes the setDone() method in exactly the same way in which it executes any other method. This point is often confusing to developers who are new to threads; it can be confusing as well to developers who understand threads but are new to object-oriented programming.

Let's suppose that we want the character in our display canvas to move across the screen until the user types in the matching character.

We glossed over the details at the time, which may have given the implication that they are minor issues. However, we must understand that when two threads share data, complexities arise. These complexities must be taken into consideration whether we're implementing a large shared database or simply sharing a done flag. In this chapter, we look at the issue of sharing data between threads. , concurrently). In this chapter, we examine the concept of a race condition and mechanisms that solve the race condition.
